After Uploading photo on server from android Application, it lost his quality

While I select the image from the gallery and shows it in ImageView. The image quality is all right. But, uploading an image on the server, it lost quality and become a blur. I obtain the image from the camera by this code.
private void onCaptureImageResult(Intent data) {
bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File destination = new File(
Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg"
);
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
imageView.setImageBitmap(bitmap);
}
Then, I did this work-
private String imageToString(Bitmap bitmap){
ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG,100,byteArrayOutputStream);
byte[] imgByte=byteArrayOutputStream.toByteArray();
return Base64.encodeToString(imgByte,Base64.DEFAULT);
}
and used this function to compress my selected photo. But, it makes the loss of that image quality and image become a blur on the server. Why am I facing this problem?

You could use the .png format as it's lossless and doesn't reduce the image quality. On the other hand the .jpeg format is just the opposite of this.
private String imageToString(Bitmap bitmap){
ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] imgByte=byteArrayOutputStream.toByteArray();
return Base64.encodeToString(imgByte, Base64.DEFAULT);
}

You did not show the intent to start a Camera app.
But you did it in such a way that you only got a thumbnail of the picture taken.
Change the intent. Add an uri where the camera app can save the full picture.
There are 783 examples of such an intent on stackoverflow and even more on the internet.

Problems saving and retrieving images

Ok i'm completely editing this post... I have made it so that I can save the file path to my data base. this works and is saved as /storage/emulated/0/1508blah blah.jpg . Now i cannot get my code to read this item back into a picture.
imagePhoto = (ImageView)findViewById(R.id.detail_recipe_image);
Toast.makeText(this, recipe.image, Toast.LENGTH_SHORT).show();
Bitmap bmp = BitmapFactory.decodeFile(String.valueOf(recipe.image));
imagePhoto.setImageBitmap(bmp);
am I missing something here? cause the Toast Is reading the recipe.image just fine and is displaying the path. why Is the rest not displaying the image?
Storage Code
private void onCaptureImageResult(Intent data) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg");
String picturePath = destination.toString();
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
textImagePath.setText(picturePath.toString());
ImageView img = (ImageView)findViewById(R.id.addphotoview);
img.setImageBitmap(thumbnail);
}

Adding in the files paths seem to be the best solution to the problem i am having so that you #ModularSynth for your help with this. Always making sure all the info is your code to make the file paths work helps.

Black portion in place of transparent portion while saving the bitmap

I am frustrated searching almost every google page for this problem.
I need to save my bitmap to file.
I have used this method several times with no problem at all. But now I am having a problem.
The Bitmap I am saving is a round image with transparency and having .png format which I have placed in res folder. But I am getting black portion in place of transparent portion.
This is the code I am using for saving the bitmap.
void saveImage(Bitmap bmp) {
try {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, bytes);
finalImg = new File(Environment.getExternalStorageDirectory(),
"emoticon_temp" + ".png");
finalImg.createNewFile();
FileOutputStream fo = new FileOutputStream(finalImg);
fo.write(bytes.toByteArray());
fo.flush();
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
I am saving this bitmap as file because I need to share this image and for sharing the image I need the Stream Uri.
If you got any other Idea for sharing a bitmap, please let me know.

The method write(byte[]) in the type FileOutputStream is not applicable for the arguments (Drawable)

Im attempting to save the actual image from my applications resources to a file on the SD card so it is accessible by the messaging application but I'm getting the error of - The method write(byte[]) in the type FileOutputStream is not applicable for the arguments (Drawable) - where its supposed to save it. I believe that I'm not using the appropriate method to save the actual image itself and I'm having difficulty finding a solution.
// Selected image id
int position = data.getExtras().getInt("id");
ImageAdapter imageAdapter = new ImageAdapter(this);
ChosenImageView.setImageResource(imageAdapter.mThumbIds[position]);
Resources res = getResources();
Drawable drawable = res.getDrawable(imageAdapter.mThumbIds[position]); //(imageAdapter.mThumbIds[position]) is the resource ID
try {
File file = new File(dataFile, FILENAME);
file.mkdirs();
FileOutputStream fos = new FileOutputStream(file);
fos.write(drawable); // supposed to save the image here, getting the error at fos.write
fos.close();
}catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

You error does explain it all, A fileOuputStream can not take a Drawable, it needs a byte array.
So you need to get the bytes from your Drawable.
try:
Drawable drawable = res.getDrawable(imageAdapter.mThumbIds[position]);
Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] bitmapdata = stream.toByteArray();
....
fos.write(bitmapdata);
And while you are at it, put the fos.close() in the Finally bock

Store Bitmap image to SD Card in Android

I am facing some strange problem with my android code,
I have an image in Bitmap variable and want to save that file to SD card.
I code as follow,
Bitmap IMAGE // Loaded from internet servers.;
try {
File _sdCard = Environment.getExternalStorageDirectory();
File _picDir = new File(_sdCard, "MyDirectory");
_picDir.mkdirs();
File _picFile = new File(_picDir, "MyImage.jpg");
FileOutputStream _fos = new FileOutputStream(_picFile);
IMAGE.compress(Bitmap.CompressFormat.JPEG, 100, _fos);
_fos.flush();
_fos.close();
Toast.makeText(this, "Image Downloaded", 7000).show();
} catch (Exception ex) {
ex.printStackTrace();
Toast.makeText(this, ex.getMessage(), 7000).show();
}
I am using Sony Experia Arc as my testing device, when the phone is connected to my computer, the code works nice, it stores image and also displays in gallery. But when I disconnect phone from my computer and test the app, it doesn't save picture and doesn't show any exception.

use this function
void saveImage() {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
String fname = "Image.jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
myBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
//4
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
try {
file.createNewFile();
FileOutputStream fo = new FileOutputStream(file);
//5
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

**This Code Cover the Following Topics**
1. Save a bitmap Image on sdcard a jpeg
2. Create a folder on sdcard
3. Create every file Separate name
4. Every file save with date and time
5. Resize the image in very small size
6. Best thing image Quality fine not effected from Resizing
The following method is used to create an image file using the bitmap
public void createImageFromBitmap(Bitmap bmp) {
FileOutputStream fileOutputStream = null;
try {
// create a File object for the parent directory
File wallpaperDirectory = new File("/sdcard/Capture/");
// have the object build the directory structure, if needed.
wallpaperDirectory.mkdirs();
//Capture is folder name and file name with date and time
fileOutputStream = new FileOutputStream(String.format(
"/sdcard/Capture/%d.jpg",
System.currentTimeMillis()));
// Here we Resize the Image ...
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100,
byteArrayOutputStream); // bm is the bitmap object
byte[] bsResized = byteArrayOutputStream.toByteArray();
fileOutputStream.write(bsResized);
fileOutputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
}
and add this in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
